  1. Draw the reference line xy and locate 0 at 20mm below it.

  2. With centre 0 and radius 15mm draw a circle forming the top view.

  3. O?l:am the front view by projection, keeping the height equal to 45mm and the base coinciding
    wlthxy.


Problem: A cylinder with base 40mm diameter and 50mm long rests on a point of its base

on HP such that the axis makes an angle of 30° with HP. Draw the projections of the
cylinder.
